A generally cylindrical planter in the form of an inverted, truncated cone includes a pail with an internal, perforated baffle that divides the interior into separate, laterally spaced apart volumes. A water level float indicator is mechanically secured by the baffle. An overfilling prevention orifice is defined in the peripheral surface of the pail overfilling with water. A smaller “weep” hole disposed beneath the overfill-preventing hole 20 is normally blocked by a removable plug that can be removed to establish a proper fill line. The generally planar baffle is disposed at an angle within the pail, intersecting the pail body to form a conic section. The baffle is angled at approximately forty to fifty degrees.
